Assessment rationale/justification
Less than 50 mature individuals exist in Bangladesh, which is a decline of >80% in the last 20 years, making this taxon extremely vulnerable to extinction in the near future. The population is also isolated from the Indian locations. Hence the higher category of Critically Endangered
